Nucleotide mismatches between the VP7 gene and the primer are associated with genotyping failure of a specific lineage from G1 rotavirus strains.

Abstract excerpt

In recent years it was reported that the accumulation of point mutations in VP4 and VP7 genes of rotavirus strains was the main cause of the failure of the G or P-typing. Failures in the correct genotyping of G1, G2, G8, G9 and G10 rotavirus strains were reported in the most commonly used reverse transcription (RT)-PCR strategies. Collecting VP7 gene sequences of G1 rotavirus strains from databases we found that...
